So here's the concept: we want to evaluate each touch by the difference between expectations and results. Input Contact: this serves as the expectation - given the situation you've been dealt, how well do we expect you to do? Output Contact: this serves as the result - looking at both terminal & non-terminal results Serving, [...]
*blue is won matches, orange is lost matches - matchid is chronolnogical from start (1) to end of season (39)* So the other evening, I was starting to draw up my first practice of the 2019-2020 season for the Bay 16-1s. It's a team that has great potential, some fantastic athletes, good height, and just [...]

But for our sake, just wanted to share some real world data from the 2019 [...]
So, this season at Harker, I convinced my AD to splurge a little and get us Volleymetrics for the spring. I'm stoked to finally get some coded data on the high school level that can hopefully inform my approach to coaching similarly skilled teams in the future - while also validating or disproving some of [...]
